About Muon Vision
Muon Vision builds muon tomography detectors for mining companies. The detectors read the flow of cosmic ray muons through rock or soil to measure density and track changes over time. This lets operators monitor leaching heaps, tailings dams, and underground voids without drilling. Operators can deploy the sensors in horizontal or vertical boreholes, or at the surface, and run them remotely, keeping staff out of hazardous zones.
Muon Vision was founded by a former MIT nuclear physicist and a former BMW engineer, and operates from Cambridge, Massachusetts, and Santiago, Chile. Tancredi Botto is the chief executive officer and co-founder. In September 2022 the company won a $978,286 Small Business Innovation Research grant from the National Science Foundation to develop technology for mine safety and yield.

Why Investors Backed Muon Vision
Muon Vision makes muon tomography detectors that monitor mining assets such as heap leach pads, tailings dams, and underground workings. The detectors read cosmic ray muons passing through rock or soil to produce continuous density data. Muon Vision's case is that this data can raise metal recovery and cut safety risks compared with drilling and lab testing. The company built the technology on more than a decade of experience with borehole-deployable muon detectors.
The problem it targets
Muon Vision's case is that mining operations face opacity, inefficiency, and catastrophic risk inside heap leach pads, tailings dams, and underground mines. Operators often rely on invasive drilling and lab test work to check fluid content, porosity, and structural stability, which costs money and exposes crews to hazardous zones. Continuous monitoring can remove these blind spots and validate the models operators use to manage the assets.
What the product does
The detectors measure the flow of cosmic ray muons through rock or soil to find density and density changes, working like a volumetric X-ray scan. Deployed in horizontal or vertical boreholes, or from the surface, the system can read through up to hundreds of meters of material. For leaching heaps, the detectors map fluid content and air-filled porosity to within 1 percent. For tailings dams, they track phreatic levels and detect seepage, and for underground mines they locate ore bodies and old workings without drilling.
Progress so far
Tancredi Botto, the chief executive officer, holds a Ph.D. in nuclear physics from Vrije Universiteit Amsterdam. He spent 13 years in the oil and gas industry on density logging before co-founding Muon Vision. In 2012 he ran the first pilot of a borehole-deployable muon detector in northern Canada. In November 2025 he presented the company's muon radiography technology at an MIT Industrial Liaison Program event on new mining technologies.
